In its native range Exacum affine is an annual or short-lived perennial and is suitable for permanent outdoor cultivation only in humid tropical and subtropical areas. Grown as a pot plant, this plant requires a well-drained, but moist potting mix. Exacum will tolerate good light but not direct sun.
There are a few perennials that save their big show for the end of the summer. Among them: Rudbeckia (yellow flowers) and helenium. The ultimate perennial garden. It's not difficult to bring that vision to mind. For me, it's a classic English border, with iris, lupine and poppies, that continues blooming right into the fall, with wave after wave of color and form: foxgloves, roses, delphinium, dianthus, hollyhocks, lilies and more.
